Thanks for the info. I must say I have never heard that adding too many
supers could lead to supersedure! You also said not adding supers could do
this! Curious! More info!

Anyway, as I said, the main objection to supersedure is if you are trying to
maintain selected lines. If I am trying to study resistant stock and half the
queens are gone in two months, what am I studying? Their daughters, of
course, but that wasn't the plan. The daughters might have half as much of
the desired trait.
